[AI-generated answer — Bot GPT 3.5]

To find the median age, we need to arrange the ages in increasing order.

Starting with the smallest ages:
- There is one person aged 28.
- The ages 31, 32, and 34 follow.
- The ages 42, 47, and 49 come next.
- Finally, there is one person aged 54.

Now, we count the total number of ages:
1 + 3 + 3 + 1 + 1 = 9.

Since there are an odd number of ages (9), the median age will be the middle value.

Arranging the ages in increasing order, we get:
28, 31, 32, 34, 42, 47, 49, 54.

Therefore, the median age is 42.

Answer 2

the median age is not 42

Answer 3
